What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
ObjectiveThe meniscus has poor intrinsic healing capacity, particularly in avascular regions. Meniscal injury is strongly associated with progressive knee dysfunction, chronic pain, and accelerated osteoarthritis development. Current treatments, such as allografts and partial meniscectomy, are limited by donor scarcity and secondary joint degeneration. Therefore, this study aimed to develop a regenerative meniscal scaffold with integrated biomechanical and biological functionality.MethodsA biomimetic composite scaffold was fabricated via low-temperature three-dimensional printing using poly(D,L-lactic acid-co-trimethylene carbonate) and bacterial cellulose. Native meniscal architecture was reproduced using micro-computed tomography-based modeling, and interconnected porosity was designed to promote cell infiltration. Material integration employed dichloromethane as a shared solvent, enabling dual-ink (poly(D,L-lactic acid-co-trimethylene carbonate) + bacterial cellulose) co-printing. Scaffold performance was assessed using scanning electron microscopy morphology, porosity and water absorption assays, mechanical testing, Fourier-transform infrared spectroscopy, and
